Description

[Technical field]

[0001] The present invention relates to the field of hair dryer technology, specifically to double duct hair dryers. [Background technology]

[0002] High-speed hair dryers are gradually becoming mainstream products in the market. Different from ordinary hair dryers, high-speed hair dryers use brushless motors, and with their unique motor-driven blades, they can reach a strong enough wind force and achieve a fast drying effect when blowing hair. Brushless motors not only have a high rotation speed, but also have a larger wind force, lower noise, and longer life. However, the homogenization of commercially available high-speed hair dryers is serious, and most high-speed hair dryers are "T" shaped, with air entering from the bottom of the handle and air exiting from the header, with a large volume and single function. At the same time, the air loss of the "T" shaped duct is large. When using a hair dryer, in addition to the need to dry hair, women also need to style their hair. However, existing hair dryers require hair styling with tools such as combs. It is very inconvenient to operate the comb with both hands. Therefore, we propose a double duct hair dryer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following describes the embodiments of the present invention in more detail in conjunction with the accompanying drawings.

[0015] The present invention provides a double duct hair dryer, and the duct and streamlining of the double air outlets 411 are designed in a straight line shape to reduce the loss of air volume in the duct and increase the air speed and volume. The duct design of the double air outlets 411 utilizes a hollow groove to place the hair in the middle of the two air outlets, increasing the contact area between the hair and the air, and improving the drying efficiency. In addition, the hollow design of the double air outlets can make it easy to perform hair styling operations. See Figure 1-5. It includes a shell assembly 1, a driving part 2, a heat conduction part 3, and an air outlet part 4;

[0016] The driving part 2, the heat conducting part 3 and the air outlet part 4 are installed inside the shell assembly 1, and the internal parts are installed through the shell assembly 1, and are installed in a straight line, so that the loss of air volume in the duct is reduced by straightening the air flow, and the air speed and the air volume are increased.

The filter hole 111: Installed on the right end of the outer wall of the housing 11, and the filter mesh 12 blocks impurities, and the magnetic suction structure makes it easy for users to disassemble and clean. The filter mesh 12: Installed on the right end port inside the housing 11, and blocks the outer hair. The tail cap magnet 13: Installed on the right end of the filter mesh 12, and restricts the filter mesh 12. Tail cap 14: Attached to the right end of the tail cap magnet 13, it fixes the filter mesh 12 to the right end port inside the housing 11. Tail stop 15: Attached to the right end of the outer wall of the tail cap 14, it can discharge the line. It is fixed to the tail cap 14 by the filter mesh 12 and fixed with a screw. A removable part of the filter mesh 12 is fixed in the gap between the housing 11 and the bracket 21. It is fixed by magnetic attraction with the magnet 27. When the user uses it for a long time, the filter mesh 12 will attract a large amount of dust and other particles. It needs to be cleaned promptly. Otherwise, the intake port will be clogged, which will avoid the operation of the motor 25, and the magnetic attraction structure makes it easy for the user to disassemble and clean;

[0017] The driving part 2 is mounted on the right end inside the shell assembly 1. The driving part 2 uses dual-emitter plasma technology to simultaneously emit positive and negative ions, and after acting on the hair, quickly neutralizes the positive and negative charges, making the hair smooth and shiny. The driving part 2 includes: a bracket 21, a button PCB board 22, a button 23, a main function PCB board 24, a motor 25, a fixing buckle 26 and a magnet 27. The bracket 21: is mounted on the right end inside the housing 11, and is provided in two sets, and the main function PCB board 24 and the motor 25 are mounted inside. The button PCB board 22: is mounted on the outer wall of the lower bracket 21, and the button PCB board 22 is electrically connected to the main function PCB board 24, so that the main function PCB board 24 can be operated. The button 23: is fixed in the button hole of the housing 11 and is connected to the button PCB board 22.

Magnet 27: Installed on both ends of the filter mesh 12, can fix the filter mesh 12. A plasma generator is installed at the upper end of the main function PCB board 24, and is connected to two holes at the top of the air duct 42 through two lead wires. The tips of the two lead wires output from the plasma generator are respectively a positive ion generator carbon brush and a negative ion generator carbon brush. Motor silicone sleeve 28: Installed inside the motor bracket 29, restricting the motor 25. The left end of the motor bracket 29 is attached to the right end inside the air outlet part 4, which can fix the motor silicone sleeve 28 and limit the installation of the heater 33.The motor 25 is wrapped in a motor silicone sleeve 28, which is fixed to the motor bracket 29. The motor silicone sleeve 28 is elastically engaged and fixed to the motor bracket 29. The motor bracket 29 has a limit step to position the motor 25 and the motor silicone sleeve 28. The fixing bracket 21 at the lower half of the motor 25 and the motor silicone sleeve 28 also has a limit step. The upper and lower limit steps jointly position the motor 25 and the motor silicone sleeve 28.

[0018] Among them, there are left and right holes at the joint between the motor bracket 29 and the air duct 42, which are used for the wiring of the motor 25 and the connection wire between the heater 33 and the main function PCB board 24 17. After the wiring of the motor 25 and the wiring of the heater 33 pass through the holes, they are sealed with a seal to ensure the sealing inside the duct;

[0019] Hair does not have static electricity when it is damp, but when the moisture evaporates due to the action of the air duct, the hair rubs against each other, generating static electricity. The friction caused by the fluid is messy, so it generates positive and negative charges. High-speed fans have a faster flow rate and are more likely to cause static electricity. The negative ions from the single-emitting pole only neutralize the positive charges of static electricity. The remaining negative charges still cause hair mess due to repulsion. The dual-emitter plasma technology simultaneously releases positive and negative ions, which quickly neutralize the positive and negative charges after acting on the hair, making the hair smooth and shiny. It has the same effect not only on the process of drying hair, but also on blow styling;

[0020] The heat conducting part 3 is mounted in the center inside the shell assembly 1, heats the blown air, adjusts the air from the air outlet part 4, divides the air volume with the blades, reduces the head loss of the air flow, increases the air speed and volume, and reduces the noise caused by the head loss. The heat generating part is not facing the air outlet but has a certain distance, so it has a good fire prevention effect. The heat conducting part 3 includes: a mica sheet 32 ​​and a heater 33. The heater 33 is composed of a mica sheet 32 ​​and a heating wire, and is fixed inside the air duct 42, and one end of the mica sheet 32 ​​is fixed in a groove at the upper end of the motor bracket 29;

[0021] The air outlet part 4 is installed at the left end inside the shell assembly 1, and the internal hollow double outlet duct design forms a pressure difference, sucks in the surrounding air in the negative pressure area, and increases the wind speed of the outlet. The double outlet duct design uses a hollow groove to place the hair in the middle of the two outlets, increasing the contact area between the hair and the wind, and improving the drying efficiency. The air outlet part 4 includes: a deflection blade 31, an upper cover 41, an outlet 411 and an air duct 42. The deflection blade 31 is installed inside the air duct 42, and can adjust the fluid movement trajectory and flow rate of the air duct 42. The deflection blade 31 divides the double outlet into three small outlets respectively, or adjusts the number of outlets by adjusting the number of deflection blades. Three deflection blades are inserted into the duct to deflect the air and change the wind direction, so that the wind direction of the outlet is perpendicular to the outlet, the air volume per unit area of ​​the double outlet is uniform, the blades divide the air volume to reduce the head loss of the air volume, increase the wind speed and volume, and reduce the noise caused by the head loss. When in use, the fluid enters the device from the intake port at the bottom of the main body, passes through the motor 25, passes through the heating rack inside the air duct 42, is divided into several parts by the deflection blades 31, and finally is blown out from the two sets of outlets 411 of the upper cover 41, completing the fluid flow path. The upper cover 41 is attached to the left end of the air duct 42, and the deflection blades 31 installed inside blow out the air vertically. The outlets 411 are attached to both sides of the front end of the upper cover 41, and correspond to and match the outlets of the air duct 42, and blow out the air blown out of the air duct 42 vertically. The upper cover 41 is installed in a U-shape, and hair can be placed inside to dry and style the hair. The air duct 42 is installed at the left end inside the housing 11, and the duct design with the hollow inside and double outlets creates a pressure difference, sucks in the surrounding air in the negative pressure area, and increases the wind speed of the outlet. When drying hair, clip the hair in the hollow part and blow in the direction of the wind to accelerate the evaporation of water from the hair. The size of the hollow part can be adjusted. When the air duct 42 and the deflection blade 31 are combined, there is a gap in the middle of the duct. The upper cover 41 covers the gap to avoid wind leakage;

[0022] 10, there is an arc angle at the outlet of the air duct 42, which can reduce the head loss of the fluid, increase the wind speed and volume, and reduce the wind noise. The size of the arc angle can be adjusted, all within the protection range.

[0023] In a specific use, a person skilled in the art will turn on the device and press the button 23 to start the button PCB board 22. The main function PCB board 24 will start in the selected mode. At this time, the motor 25 and the heater 33 will start to work, and the hair will be placed inside the upper cover 41, and the hair will be packed in the middle of the two air outlets, increasing the contact area between the hair and the wind, and improving the drying efficiency. The air outlet 411 is where the fluid enters the device from the intake port at the bottom of the main body, passes through the plasma generator and the motor 25, passes through the heating rack inside the air duct 42, is divided into several parts by the deflection blade 31, and finally blows out from the two sets of air outlets 411 on the upper cover 41. At this time, the air is blown out vertically from the air outlet 411. The duct design with the internal hollow double air outlet creates a pressure difference, sucks in the surrounding air in the negative pressure area, increases the air speed of the air outlet, and dries the hair.
